What is the average lifespan of a person with Sanfilippo syndrome?
Children who have this genetic error of metabolism show no signs at birth. As the disease progresses, they slowly lose the ability to speak, walk, and eat. There’s no cure for Sanfilippo syndrome. The current life expectancy is 10 to 20 years.
What happens to people with Sanfilippo syndrome?
Mucopolysaccharidosis type III (MPS III), also known as Sanfilippo syndrome, is a progressive disorder that primarily affects the brain and spinal cord (central nervous system). It is characterized by deterioration of neurological function (neurodegeneration), resulting in many of the features of the condition.
Can Sanfilippo syndrome be cured?
There is no cure yet for Sanfilippo syndrome. Treatment focuses on easing symptoms and giving a child the best quality of life for as long as possible. But some tests and clinical trials (for instance, with enzyme replacement therapy and gene therapy ) have many doctors believing that help could be on the way.
What causes death in Sanfilippo?
Causes of Death in Children With Sanfilippo “Pneumonia accounted for more than 50% of deaths in patients with Sanfilippo syndrome type A. Cardiorespiratory failure, gastrointestinal complications, central nervous system complications and other causes were responsible for 11%, 4%, 4% and 30% of deaths, respectively.”
Who is most likely to get Sanfilippo?
Sanfilippo syndrome is seen in 1 in 70,000 births in the U.S., and children with it have a life expectancy of 10 to 20 years. While it’s considered a rare disease, having a family history of it increases the risk for your child.
What are the 4 types of Sanfilippo syndrome?
Sanfilippo syndrome is divided into four subtypes, which are differentiated by their genetic cause: MPS IIIA, IIIB, IIIC, and IIID. All four subtypes of Sanfilippo syndrome primarily affect the brain and spinal cord. Over time, other body systems can also be affected.
Does Sanfilippo run in families?
How is Sanfilippo inherited? Everybody has two copies of each gene, one inherited from their mother, and one from their father (with some exceptions). Sanfilippo is an ‘autosomal recessive disorder’. This means that for a child to inherit Sanfilippo, he or she must get one faulty gene from each parent.
How many kids have Sanfilippo?
This eventually leads to organ damage, mental and growth disorders, and behavioral problems. Sanfilippo syndrome is seen in 1 in 70,000 births in the U.S., and children with it have a life expectancy of 10 to 20 years.
Why is there no cure for Sanfilippo?
Because of its neurodegenerative nature and multi-system impact, Sanfilippo Syndrome is often called “childhood Alzheimer’s” or “childhood dementia.” Currently there is no FDA-approved treatment or cure.

Cardiorespiratory failure, gastrointestinal complications, central nervous system complications and other causes were responsible for 11%, 4%, 4% and 30% of deaths, respectively (Fig. 3a).
What is Sanfilippo syndrome?
Sanfilippo syndrome is a genetic error of metabolism. It is a mucopolysaccharidoses, an MPS disorder, MPSlll. Mucopolysaccharides are long chains of sugar molecules, which are used in building connective tissues.
What causes Sanfilippo syndrome type D?
Sanfilippo Type D is caused by a deficiency in N-acetylglucosamine 6-sulfatase. Sanfilippo syndrome was first described in 1963 by Dr. Sylvester Sanfilippo and is considered rare, with an occurrence of 1 in every 70,000 births. It is an autosomal recessive hereditary disorder, which means,…
What are the chances of having a child with Sanfilippo syndrome?
There is a one in four chance of having a child born with Sanfilippo syndrome. There is a two in three chance that unaffected children will be carriers. Sanfilippo syndrome is a progressive disorder, meaning that at birth the children appear typical and do not show signs of the disorder.
What is the role of mucopolysaccharides in Sanfilippo syndrome?
Mucopolysaccharides are long chains of sugar molecules, which are used in building connective tissues. When the body is finished using these molecules, it breaks them down, with enzymes, and disposes of them. Children with Sanfilippo syndrome are missing or are deficient in the enzyme to break down the molecules.
